The New ASU Story: Landmarks

The 1989 addition to Hayden Library, a two-level underground expansion,
added 97,000 square feet with seating for 1500 patrons and shelf space for 375,000
new volumes. The new entrance is a courtyard 15 feet below mall level, which ties
into the existing lower level of the library. The second level is below the
courtyard level. The underground addition was designed for long term expansion
to the west. Architect: Architecture One, Ltd. And Sasaki Associates, Inc.
